Django 1.5.1, SQL Server 11 (aka 2012), django-mssql 1.3.1. If adding a date field in a model a datetime field is created in SQLServer. If trying to set a date in the admin interface (or a similar custom interface), an internal server error occurs because SQLServer cannot convert the string (e.g. "2013-08-16") to a datetime. If using a date field instead (in DataBaseCreation.data_types) this works correctly. Note that the date field is only available since SQL server 2008, so this can be changed only for the latest 2 versions.
